Panasonic ToughBooks are the world's most rugged Linux laptops. Models include the Wasp CF-19 tablet, weighing 4.5 pounds, and Tarantula CF-30, weighing 7.9 pounds. Each features a daylight-readable screen (up to 1000 NIT), touchscreen LCD, and fully rugged design for the harshest of environments (independently MIL-STD-810F tested). Both offer Linux-supported internal EVDO cellular mobile broadband options. The larger, semi-rugged Scarab CF-52 has a 15.4" 1920x1200 LCD and ATI video, making it an ideal engineering workstation for the field. Look to the 2 pound Ant CF-U1 UMPC for the smallest fully rugged machine anywhere, with a 4 foot drop specification.
